الشنطة خضرا.

In Levantine Arabic, the verb to be is usually not said in the present tense.

So instead of saying:

• The bag is green

you simply say:

• الشنطة خضرا

This is very normal in Arabic.
If you wanted a past or future meaning, then Arabic would use extra words or verbs, but in the present tense, the is/am/are idea is usually understood automatically.

In Arabic, adjectives normally come after the noun they describe.

So:

• الشنطة = the bag
• خضرا = green

Literally, the order is:

• the bag green

That is the normal Arabic pattern, unlike English, where adjectives usually come before the noun.

Because الشنطة is a feminine noun, the adjective also has to be feminine.

In Arabic, adjectives agree with the noun in things like:

• gender
• number
• definiteness

So:

• masculine: أخضر = green
• feminine: خضرا = green

Since شنطة is feminine, you use the feminine adjective form: خضرا.

A very common clue is the ending ـة (called taa marbuuTa in formal grammar).

Words ending in ـة are very often feminine, and شنطة follows that pattern.

So a learner will often recognize:

• شنطة → probably feminine

That is why the adjective becomes feminine too.

This is a very common difference between spoken Levantine and Modern Standard Arabic.

In Modern Standard Arabic, the feminine form of green is usually:

• خضراء

But in Levantine speech, people commonly say:

• خضرا

So خضرا is the natural colloquial Levantine form.
It is shorter and matches everyday pronunciation.

Because ش is a sun letter.

In Arabic, when الـ comes before a sun letter, the l sound disappears and the next consonant is doubled.

So:

• underlying form: ال + شنطة
• spoken form: اشّـ / الشّـ...

That is why learners hear something like:

• ish-shanTa
• or ash-shanTa

The exact vowel can vary a bit by dialect and speaker, but the key idea is that the l is not clearly pronounced before ش.

خ is a sound that English does not really have.

It is pronounced in the back of the throat, like a rough, breathy sound. Many learners compare it to:

• the ch in Scottish loch
• the j in Spanish José in some accents
• the German Bach

So خضرا starts with that rough throat sound, not with an English k or h.

ط is an emphatic version of ت.

It is heavier and darker than a normal English t.
Your tongue is still near the t position, but the sound has a thicker quality.

So شنطة is not exactly shanta with a regular English t.
It is closer to shanTa, with a strong, heavy T sound.

This sentence is a nominal sentence: a noun phrase plus a description.

• الشنطة = the bag
• خضرا = green

In English, we say the bag is green, and green does not need the.
Similarly in Arabic, the predicate adjective here does not take الـ.

So خضرا is correct in this kind of sentence.

Yes, but the meaning changes.

• الشنطة خضرا = the bag is green
• شنطة خضرا can mean a green bag

So with الشنطة خضرا, you have a full sentence.
Without الـ, it can sound more like a noun phrase rather than a complete statement, depending on context.

This sentence is best understood as Levantine colloquial Arabic.

The biggest clue is خضرا, which is the spoken feminine form common in Levantine. In Modern Standard Arabic, you would more often see:

• الحقيبة خضراء for the bag is green
• or sometimes الشنطة خضراء if using the word شنطة

So the sentence you were given is natural for everyday spoken Levantine.

A common pronunciation is roughly:

• ish-SHAN-ta KHA-dra
• or ash-SHAN-ta KHAD-ra

The strongest stress often falls around:

• SHAN in الشنطة
• KHAD or the first syllable of خضرا

Stress can vary somewhat by region and speaker, but if you say it with a clear doubled sh in الشنطة and a strong kh in خضرا, you will sound much more natural.
